  Add callback to git_objects_table This adds create and free callback to the git_objects_table so that more of the creation and destruction of objects can be table driven instead of using switch statements. This also makes the semantics of certain object creation functions consistent so that we can make better use of function pointers. This also fixes a theoretical error case where an object allocation fails and we end up storing NULL into the cache.
